Thousands of white cranes flocked to Momoge Wetland. What are the migration habits of white cranes?

Jilin Momoge National Nature Reserve welcomes migratory birds to the south, and more than 2,000 cranes come to Momoge National Nature Reserve to dock and transport. Due to the heavy precipitation in spring and summer this year, the water level in the upper reaches of Momoge Wetland rose, and the wetland water volume was deep, which had a certain impact on crane stop. Red-crowned cranes fly from the south of China to Siberia to breed, and return to the south with live red-crowned cranes when the weather turns cold in autumn. According to the statistics of the staff in the reserve, the proportion of young cranes this year is about 1 1%. The crane will stay in Momoge Wetland for about 20 days to feed, and then fly to Poyang Lake for the winter.

Cranes usually live alone, in pairs or in groups, but most of them are large groups. The crane is very alert. In order to ensure the safety before sunset, cranes gather from all directions to dive in the lake for the night. Early in the morning, they flew to shallow water with rich food, stood guard, looked around and called for distant companions, and soon there were many, many. In particular, large groups of hundreds or even thousands of people gathered before migration were swept away by the updraft overnight. These signs seem to be pre-arranged and very harmonious with each other, which is difficult for us to understand. The reason why cranes come to Momoge wetland on time in spring and autumn every year is because cranes with the strictest requirements for habitat have a strong attachment to shallow wetlands.

Momoge Wetland has more than 1 10000 acres of fresh water and open wetlands. White cranes like to eat plants, aquatic plants and animal foods. The purpose of their coming here is to quickly replenish food and lay the foundation for their breeding in the north and winter travel in the south. Migration ensures that cranes live in the best climate conditions, which is conducive to obtaining rich and diverse food sources, breeding and expanding living space, natural balance and evolution. It is a mystery in nature that a crane can determine its direction from thousands of miles away. It shows the family and group foraging activities of cranes in Momoge wetland in the morning and evening, especially the wonderful moment when cranes fly in the air during migration. ?
